框架是什么,为什么要用框架. 框架解决了什么.
我是刚学的. 把一简单的select  结果放到网页上.

直接写点php 代码就行了.
用框架干什么. 整个框架一大堆代码,读也读不懂.鬼知道里面发生了什么事.
而且要用框架,还要花很多时间学习它.

我"把一简单的select  结果放到网页上" 这件事上,我感觉框架屁用没有.

网上只说框架方便程序员,做了基础工作. 都是一些废话.
谁能举行个实例说下,框架到底起到了什么作用.


------解决方案--------------------
框架有点像类库

比如处理数据使用ORM类 自动处理URL 动态静态切换 权限系统
如果不是你还得做很多工作

queryphp 框架基本是类库

------解决方案--------------------
不要被“名词”吓到,也许同样的“名词”会变成你手中的“法宝”

什么是“框架”,框架是应用程序“模板”
就好比“八股”文章,不论好坏,按照规则填填就是

什么是“应用程序”,应用程序是完成某项特定任务的代码堆砌
也可以说是“套路”
当你完成了一、二个项目后,你是不会放弃承载着你大量心血的“代码集”的
你会在第三、第四...个项目中重复你的思路、代码,当然也包括改进或创新
于是,“框架”出现了......



------解决方案--------------------
框架,只是简化了程序员的工作。
将很多的类库集成到一起。
你会用框架就行,不需要理解框架是怎样做到这一点的。它是怎样做到的。 这些你可以不理。当然你想做一个出色的程序员,去理解是有必要的
------解决方案--------------------
对你现在的水平,框架是一个垃圾,或者以后也是

不信你直接输出 echo 'Hello you.'; 和在框架下输出字符 Hello you看有什么区别?

再分别循环十万次输出看那个效率?

对于以上两个问题你能说出结果,并测试过,就知道框架有什么用,什么时候用,能真的解决问题吗。

这句牛。。。

仅个人感受。
我是用ci 框架的。
用后和用前的差别。
1 我不再为一些基础类库去烦了。
2 我知道配置在哪,模版在哪,如何写helper 如何去libraries 如何hook,如果是以前,自己单独写这些时,经常因摆放位置不当到处找文件。
3 框架提供了很多很好的服务。
4 如果你觉得框架垃圾,请先在工资上超越用框架的人。个人觉得,楼主这心态,工资不会超过5000.
